WASHINGTON D.C. (Newspath/WUSA) — About 70 D.C. police cadets searched the grounds and interior of the homeless shelter, perhaps a sign of how little progress police have made in their hunt for eight-year-old Relisha Rudd.

She was last seen at her school in February. It’s been exactly seven days since police found the wife of the man suspected of having her beaten to death at the Red Roof Inn in Oxon Hill.
